How did automatic flying plant protection drones win the market?

Compared to the relatively complex remote control operation, plant protection drones are more inclined towards automatic flight, which is closely related to the application scenarios and training costs of plant protection drones, and can be said to be an inevitable choice in the market.Why do we need to fly automatically?The remote control of consumer grade drones emphasizes touch, fun, and driving excitement, which is completely different from the flight of plant protection drones.Plant protection drones generally rely on round-trip routes and require precise control of flight routes and distance. At the same time, in order to avoid the phenomenon of heavy spraying and leakage, plant protection drones also have high accuracy requirements for speed and altitude.
